Hi all, If I define the following prefixes in my RDFa document <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance#" xmlns:xsd="http://www.w3.org/2001/XMLSchema#" xmlns:owl="http://www.w3.org/2002/07/owl#"> The W3C validator [1] returns an error: Line 3, Column 55: value of fixed attribute "xmlns:xsi" not equal to default. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance#" while xmlns:xsd does not produce such an error. Removing the # in the end of the xsi prefix fixes the error, but I wonder if it's correct to do so to see prefixes finishing by / or #. [2] says: > Schema Component Constraint: xsi: Not Allowed > The {target namespace} of an attribute declaration, whether local or > top-level, must not match http://www.w3.org/2001/XMLSchema-instance > (unless it is one of the four built-in declarations given in the next > section). > Note: This reinforces the special status of these attributes, so that > they not only need not be declared to be allowed in instances, but > must not be declared. It also removes any temptation to experiment > with supplying global or fixed values for e.g. xsi:type or xsi:nil, > which would be seriously misleading, as they would have no effect. Is that related to the above issue? regards, Stéphane. [1] http://validator.w3.org/check [2] http://www.w3.org/TR/xmlschema-1/#no-xsi
